( SHEETS-SHEET 6 V1. scALNEcK. CAR DUM P|NG DEVICE. FILED IUNE4 192i Figure l2 is a View similar to Figure 1l. showing the choclrmoi'ed to an inope 'ativo position.

This improved car dumpingdevicc iiicludes a. trestle structure having supporting standards l which nare-braced by cross bars Zand diagonally bracing bars 3 and carriesv spring l() so that when the cai'` is inthe dumping position shown in Fig. Ll, the plunger may be moved against the action ott-he spring. A hopper 11' is positioned adjacent the `frame 6 and beneath the rails -i and is supported by posts l2 so that coal or other material in-'the cars may be caught when delivered upon a pile below the trestle. A platform 13 is supported adjacent n this hopper and is provided with a protecting vplate lt which is positioned atpthe bottom of an abutment l5.

In order to dump the cars 16 as shown in Fig. lathe trestle has been provided with a main tilting or dumping section i7 land an auxiliary tilting or dumping .section i3 which is hingedly connected with the 'main tilting section by hinges 19. Supporting bars 20 extend downwardly tromy beneath the free end portions ot the auxiliary tilting sectionvand carry a. cross bar 21 having an opening formed therein to receive the plunger 22 which is vyieldably held in the position shown in Fig. 2 by the 'springs This plunger engages the abutment l5 and, there fore, the support 20 will. be normally held in a vertical position as shown in Fig. 3 but may bemoved to the inclined.positionfshown in Fig. 4. The space between the rails 24 of the auxiliary tilting Section is lett' clear so that there will be nothing to obstruct the passage-of the coal from the lcar down into the hopper 11 when vthe main tilting or dumping section swings upon the pivot shaft A 25 but the side rails 26 of the' main tilting section. are Connected by cross-beams 27. one of which is engaged by a spring QS which has Aits lower endl connected'with a cross beam 29 carried by certain of the braciner beams 3 and serve to yieldably retain t e maintilting or dumping section in a horizontal position. y

When ya loaded car is approaching the tilt ing sections of the trestle, it is desired. to prevent a car `from moving too close to the tilting sections until a car which is being dumped has moved off from the two tilting sections and in order to temporarily hold the approaching car against movement along the tracks, there has been provided a chock vto the side of the yplatform 32 and is con;

`and is slidably connected with the ytrestle mounted in an opening formed in the rails `chock in an inoperative position while'lthe rrails as shown in Figli. dlt will thus be 30 which is movable into and out 'of Aan operative position as shown in Figs. l1 and l2 and is carried by an arm 3l which is slidably i connected. with the supporting platform 32 by a strap 33. This arm 31 is connected with a bell cranklever 34 pivotally mounted upon the platormBQv as shown at 35 and has its second arm connected with -a draw rod 36. This rod 36 is extended outwardly 75 nected with the upper end of an arm which extends upwardly from the rod 37 which rofl 37 extends longitudinal-ly ot the trestle as shown in Fig. 2 vand aboutthe housing 3S by the guide 39. A bell cranl; lever Ll() is pivotally connected with the support 20' of" the auxiliary tilting sectionand has one arm.. connected with the rod 37 and the l'second arm connected with a Vplunger 41. This S plunger ll extends upwardly/to a point above the rails or tracks of the auxiliary tilting section and is connected with the ear l2 of the strip 45. A pi'n43 is slidably 9() and is engaged by a leaf spring llt and also by the strip 45 so that the wheel of a car can easily move into engagement with the chock actuating mechanism and hold this ai which has been emptied is moving oit ofV the auxiliary tilting sectionr of the trest'le and a loaded car is moving towards the main tilting section beyond the chock. After the car which has been emptied has passed yolif of the auxiliary tilting section, the chock actuating mechanism will be released and the springs'illl will return it-to the normal positionwith the chock extended across the seen that the ca-rswill be permittedto pass `onto the tilting Astructure in the vproper timed relation.

'The track or trestle isinclined somewhat towards the main tilting section so that a car w coast onto the tilting section. but ocra. onzilly a car will not move a the with sulticient speed to properly more upon the tilting section and. thereforen there h been provided means Itor lengaging' the 115 cui' and moving it upon the main tilting"- rdudes :i spri'iclet n l" u'lniitli p 41S? thesproclrct bein( f a mounted up beine; a di ted upon a driving I.: ci, shalt sprocket chain carries a car engaging arm which engag i the car and will push thev var upon th(` main tilting sertio'nin caso the cai' doe'.s not more along the tracks a. siuicient distance to rest upon the main tilt' ing section.

`When the loaded is on the main tilting Sectio-n and the main tiltingv sectionswings to the position shown in Fig. 4,'it is neces# sary to prevent the car from moving downwardly and it is also necessary to prevent the car 'from vmoving oil of the main tilting section onto the auxiliary tilting sectionbefore its load has been dumped into thev hopper. In order to do so, there has' been provided a. block 52 which is pivotally connected with a bracket 53 carried by one of the cross beams27. This block 52 is provided with a lever arm 54 which is connected with a link 55 which-extends downwardly and is pivotally connected with the rocker arm 56.` This rocker arm 56vis iulcrumed as shown at 57 and is loosely connected-with the crank extension 58 of the crank shaft 59. rllhis crank shaft is mounted in hanger brackets 60 and provided with a second crank extension 61 which is connected with a rod 62, the rod 62 being carried longitudinally oi the main tilting section and having its forward end co-nnected withfthe rocker arm' or lever 63. This lever 63 extends upwardly above the track and carries a roller 64 for engagement by a strip 65 mounted upon the car so that after the block has been moved to a lowered position the roller may -engage the strip 65 and the mechanism thusretained in the position shown in Eig. 5 until the car has left the auxiliary tilting sectiom Itl will thus be seen that the spring .66. whichV engages the rocker arm 56 cannot return the blockQ to the raised position until the'ca-r has moved ofi" of the auxiliary tilting section and premature return of the block to the raised or operative position will. be prevented. In order to move the rocker bar 56 to draw the link 55. downwardly, there has been provided a` bell crank lever v67 which is. pivota-lly connected with one of the cross beams 27 and has one arm provided with aV pin 68,101' engaging the rockerbar 56 and has its second arm connected with a push rod 69 which extends rearwardly be tween the rollers 7() carried by the brackets 7l. This push bar 69 carries an abutment 72 for engagement by a pin 73 which extends transversely from the wheel 74 mounted upon a, shaft 75. This shaft 75 carries a sprocket wheelv76 which is engaged by a` sprocket chain 77 for transmitting rotary movement from the sprocket wheel 78 of the driving shaft 50. It will thusbe seen that when the driving'shaft 50 is. rota-ted by the sprocket chain 79 which passes about the sprocket wheel 8O of the shaft 50 and about a sprocket wheel mounted upon the shaft of a motor mountedin the lower portion of the housing 38` the wheel 74 will be rotated and the pin 73 may engage tl'le bar f 69m move the bar forwardly and swing the rocker bar 56 to draw the block''Q to the inoperative position, The wheel 7d in addition to the pin 73. carries@ 0er. elle? pin 8l for engaging the car after thebilock tending towards the track.

When this device 1s in use7 tl'ie'loaded cars .onto the Inainv tilting section.

The door 82 of the car 16 is provide-d with a keeper 83 which extends beyond the'sides of the door for engagement by the bell crank 'latching levers 84. These latches'Si are piv- Oft-allyV connected withv the sides of the car and arepconnected by across rod 8.5 which extends beneath'the car and these latches 84V l are connected with actuating arms y8.6 by

links 87. These arms 86-are pivotally connected with thecar and connected by a cross rod 88v and, these arms are provided with side flanges one of which will be engaged by f a'releasing device as shown in Fig. 9. e This releasing device is provided withv the arm 89 for enoavinv the'flanffe 86 and this arml LP; D b

is carried bya standardv 89 which is'exten'ded bearings 90 so that the shaft may rotateV and Springs 91. are connected with side arms 92 whichfextend from the standard 89 and will .into the housing 38 and iou'rnaled in the serveto yieldablv' retain the standard against rotation with the abutment arm 89 eX- inove along the trackuntilihe firs-tear is stopped by the chock. be Ymovedl to one side to permitthe' first car `-to pass and return to thel operative position to engage and stop thesecond car. The vfirst car will' coast along the Vtrack "to themain tilting'section and if it'does; not-'move with ordumping section? thevv pin 5l `will engage theo'ar as shownin Fig., 3 and move theA car. As the car The chock can then i lsufficient speed toroll upon the main tilting moves upon the main tilting sectiom'the arm 89" will engage the outstanding flange of the "lever arm 86 upon that side 'of the car andy the latch will be moved to the inoperative position thus releasing the door 82.' The `car will* roll, upon the main. tilting section Vuntil 1t engages .the abutment block 52v which will stop its movement and the weight of the car will cause the main tilting section to tilt forwardly to t-he position showninlFig; i.

The auxiliary tilting section will alsoftilt as shown and the rear endy portion of the car will engage the bumper l0 thus retaining and as .the wheel 74 rotates fthe pin 73 will engage the abutment 720i 'the bar 69 and rocklithe bell crank lever 67 tofswingtherocker'bar't downwardly andfdraw the 15o-ck 52 to the lowered position. The pin 8l will then engage the car and move the car 'forwardly with the strip 65 engaging the roller ot' the lever 63 and retaining the abutment lock in the lowered position until the car has passed off of the auxiliary tilting section. As the ear moves across the auxiliary tilting section, the wheel will engage the strip 45 and press it downwardly thus moving the plunger 41 downwardly and rocking the bell crank lever 40 to move the rod 37 longitudinally and rock the bell crank 34 to draw the block 30 to the inoperative position and thus release the next car and permit it to travel towards the main dumping section. It will thus be seen thatthe cars will move towards the main dumping section in the proper timed relation, each car in its turn being released and permitted to move towards the dumping section by the empty car which-is passing off ofthe auxiliary tilting or dumping section. A car dumping device has thus been provided which will be substantially automatic n its operation and will be very eiiective in use.
